If 18.7 mL of 0.14 M MgCl2 are mixed with 24.2 mL of 0.52 M NaOH, what will be the final concentration of Mg2+ in solution when equilibrium is established? Assume the volumes are additive. Ksp = 1.2 10-11 for Mg(OH)2.
Here is the same problem but with different numbers. Watch that you dom't make the same mistake I did the first time through it.
